Charles H. Spurgeon on Psalms 35:3

"Say unto my soul, I am thy salvation." Observe, 1. That salvation may be made sure to a man. David would never pray for that which could not be. Nor would Peter charge us with a duty which stood not in possibility to be performed. 2Pet. 1:10. "Make your election sure." And to stop the bawling throats of all cavilling adversaries, Paul directly proves it: "Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?" 2 Cor. 13:5. We may then know that Christ is in us. If Christ be in us, we are in Christ; if we be in Christ, we cannot be condemned, for (Rom. 8:1) "There is no damnation to them which are in Christ Jesus." But I leave this point that it may be sure, as granted; and come to ourselves that we may make it sure. The Papists deny this, and teach the contrary, that salvation cannot be made sure; much good do it them, with their sorry and heartless doctrine! If they make that impossible to any which God hath made easy for many, "into their secret let not my soul come." Gen. 49:6. Observe, 2. That the best saints have desired to make their salvation sure. David that knew it, yet entreats to know it more. "I know thou favourest me" (Psalm 41:11); yet here still, dic animae, "Say unto my soul, I am thy salvation." A man can never be too sure of his going to heaven. —Thomas Adams.
